What is a Tariff Impact Calculator?

A Tariff Impact Calculator quantifies how changes in tariff rates affect your business — specifically your unit costs, profit margins, shipment-level costs, and required price adjustments. In the volatile trade environment of 2026, with tariffs fluctuating based on geopolitical developments, this tool helps businesses scenario-plan and make data-driven sourcing and pricing decisions. Whether you're a manufacturer deciding between domestic and overseas suppliers, or a retailer calculating how much of a tariff increase to pass on to customers, this calculator shows the real numbers.

How Does It Work?

Enter your current FOB unit cost, existing duty rate, proposed new duty rate, current selling price, and shipment volume. The calculator compares your old and new duty per unit, calculates the extra cost per shipment, and shows how much you'd need to raise prices to maintain your current profit margin. It also estimates the profit margin erosion if you absorb the tariff increase.

Formula

Old Duty/Unit = FOB Unit Cost × Current Rate%\nNew Duty/Unit = FOB Unit Cost × New Rate%\nExtra Cost/Unit = New Duty − Old Duty\nTotal Extra Cost = Extra/Unit × Units per Shipment\nPrice Increase Needed = Extra/Unit ÷ Selling Price × 100%\nMargin Erosion = Extra/Unit ÷ (Selling Price − Cost − Old Duty) × 100%

Who Uses This Tool?

• Importers evaluating the impact of new tariff announcements
• CFOs modeling pricing strategies under different tariff scenarios
• Sourcing managers comparing total cost from different origin countries
• Retail buyers deciding whether to absorb or pass through cost increases
• Trade compliance teams preparing for policy changes

Pro Tips

• If margin erosion exceeds 20%, consider these options: (1) renegotiate with suppliers, (2) shift sourcing to FTA partner countries, (3) redesign product to qualify for a lower tariff classification
• Use tariff engineering — small design changes can sometimes shift your product to a lower-duty HS code.
• Monitor USTR exclusion processes — if no domestic producer makes what you import, you may qualify for a tariff exclusion.
• Don't make long-term sourcing decisions based on temporary tariff spikes. Tariffs change; supply chains don't.

Frequently Asked Questions about Tariff Impact Calculator

How do I know what the new tariff rate will be?

Monitor USTR (ustr.gov) for US tariff announcements. Subscribe to trade publications like the Journal of Commerce. Your customs broker can also provide rate forecasts. This calculator works with any hypothetical rate — use it for scenario planning.

Should I pass tariff costs to customers?

It depends on your competitive position. If you're the only supplier, you can likely pass through most or all of the cost. In competitive markets, you may need to absorb some costs to maintain market share. Use our calculator to model different pass-through scenarios.
